[Gluster-users] Expand distributed replicated volume with new set of smaller bricks

[Nithya Balachandran]

Yes this is possible. Make sure you have cluster.weighted-rebalance enabled
for the volume and run rebalance with the start force option.
Which version of gluster are you running (we fixed a bug around this a
while ago)?

Regards,
Nithya
